The collected materials are prepared and labelled. In addition, appropriated literature are used for taxonomical examination of the obtained material. The Keywords: altitudes and coordinates of localities and collection dates are presented. A total of 3 species in 2 genera Schizoprymnus of Brachistini are determined. From these species Foersteria polonoca Fahringer, 1934 is firstly record in Polydegmun the fauna of Turkey. However, Schizoprymnus (Schizoprymnus) bidentulus (Szépligeti, 1901) and S.(S.) Parasitoid elongatus (Szépligeti,1898) have been discovered. These two species are for the first records in the Malasie research area. Braconidae, Yu Tobias © 2019. Turkish Journal Park Academic.

Introduction Braconidae after Ichneumonidae is the second largest family the forewing of Brachistins absent and the body is small (2- of Hymenoptera (Aguiar et al., 2013) include more than 2.5 mm). It is distinguished by a clearly manifest tendency 21,220 species under 1,100 genera of 45 subfamilies. for the fusion of the first few abdominal tergites into a shield Brachistini Foerster, 1863 is the largest tribe of Brachistinae (Tobias, 1986). Brachistini is distributed in 209 countries of Foerster, 1863 with 416 species under 11 genera (Yu et al., Afrotropical, Australasian, Nearctic, Neotropical, Oceanic, 2016). Almost all species of Brachistini are endoparasites of Oriental and Palaearctic zoogeographic regions, and larvae of Coleoptera (van Achterberg, 1988)(especially on the families Curculionidae and Apionidae and about 25 other introduced into Columbia, Ontario, Florida, Louisiana, families of Coleoptera), which also include very important Mississippi, New Jersey and Texas for biological control (Yu agricultural pests. Some species of Brachistini are very well et al., 2016). known to be egg-larval parasitoids and this habit may prevail The tribe Brachistini is recognizable by Propodeum dorsally throughout the tribe (Shaw and Huddleston, 1991). carinate, and rugose all over; second analis (2A) not present Brachistinae is certainly close to Helconinae and is always in hindwing; Dorsope of first tergite absent (van Achterberg, considered as its tribe (van Achterberg, 1990; Shaw and 1993). The first three abdominal tergites separated; articulation between 1st and 2nd tergites movable Sternauli Huddleston, 1991). However, the 2nd radiomedial vein on usually smooth (Tobias, 1986).

University, Faculty of Science and Art, Department of Biology The tribe Brachistini Foerster, 1863, was already included in the subfamily Helconinae Foerster, 1863 (van Achterberg 3.Results 1988, 1990, 2000), but because of recent results of DNA analyses (Belshaw et al., 2000) the tribe is treated by van In this study, the collected and prepared materials were Achterberg (2003a) as a subfamily, similarly as by Tobias carefully analyzed. A total of 3 species were identified under (1986) and Belokobylskij (1998). Already the only recent key 2 genera. Foersteria polonoca Fahringer, 1934 is recorded for to the subfamilies of Braconidae was that published by Tobias the first time in the fauna of Turkey. (1986). This key contains 20 subfamilies and the Tribe Brachistini placed in the subfamily Brachistinae (Tobias Subfamily: Brachistinae (1986). This tribe is not well known in the Turkish fauna. Tribe: Brachistini Foerster, 1863 Prior to this study, only on the Turkish Brachistini fauna was Genus: Foersteria Szépligeti,1896 conducted six studies: Foersteria polonoca Fahringer, 1934 Three closely involved Palaearctic genera of the subtribe Material examined: Bitlis, Nemrut Dağı, Kaldera, Ilık Göl, Brachistina, Foersteria Szépligeti, 1896, Polydegmon Foerster, (Allium sp., Anchusa sp., Astragallus sp., Cyperus sp., Euphorbia 1863 and Chelostes van Achterberg, 1990 are revised and sp., Hypericum sp., Juniperus sp., Quercus sp., Pinus sp.), illustrated. The Holarctic genera of the Brachistina are keyed (38°37’10’’K, 42°14’28’’D), 2485 m. 18.06.2015, 2♀, 17 ♂; and from Turkey are described two new species. The genus 07.06.2019, 2♂. Aliolus Say, 1836 is synonymized with the genus Eubazus Nees, 1814 (van Achterberg, 1990). A new species Diagnosis: Face coarsely transversely rugose and 0.88x as Schizoprymnus erzurumus Belokobylskij, Güçlü and Özbek, long as its wide; antenna with 26 segments; first flagelomera as long as 2003 (Hymenoptera: Braconidae, Brachistinae) is described second; subapical antennal segments of female slender; ratios from Turkey (Belokobylskij, et al., 2003). A new species of ocular-ocellar line: diameter of posterior ocellus: postocellar line = Chelostes subrobustus Yilmaz and Beyarslan, 2009 is 20: 5: 8; occipital carina complete; stematicum smooth and described and the Chelostes species of the world are keyed by glabrous; apical rim of clypeus distinctly differentiated from Yılmaz and Beyarslan (2009). Then Beyarslan (2011) has remainder of clypeus; length of eye in dorsal view 0.76x recorded a new species Eubazus (Brachistes) aydae temple and temples parallel-sided or slightly widened behind Beyarslan, 2011 from the Turkish Thrace and Central eyes; hind femur dark brown or infuscated, if completely Anatolia region and new species was described, its yellowish then second metasomal tergite completely and morphological diagnostic characters were illustrated.
